See osm.org/relation/4049147#map=18/41.61794/-4.70721 - bus routes must contain *only* some parts of the roundabouts they go through.

Dear Ekaterina,

Please note that you broke a bus route relation (osm.org/relation/4049118). iD does not show the relation, but validators (and JOSM) will display the route line as broken (i.e. the members of the relation should form one single unbroken line)

I must ask you and your team to take care of not breaking such relations when you're editing roundabouts.
